The requirements are that fire protection shall be provided, the minimum water pressure at the top of the apartments is to be 240 kPa and the maximum system pressure is to be 550 kPa. The following assumptions may be used: Each of the four apartment buildings is occupied by 50 residents. Each apartment building is four stories high. Each story is 3 meters high. Each house is occupied by three residents. Average daily demand for the village is 500 Lpcd and the peak hourly demand factor is 6.2. Needed fire flow for the houses is 230 m3/h. and for apartment building is 500 m3/h, with 2 h duration. System pressure is to be provided from the elevated storage tank. Minor pressure losses in buildings may be ignored. The distribution system will not contain any loops.
